词法分析增量训练之后，再加载自定义词典，词典失效

在词法分析增量训练之后，再加载自定义词典，进行分析，发现自定义词典中定义的词不起作用，自定义词典也是完全按照这里指定的类型设置的，难道自定义模型和自定义词典不能同时加载使用吗？两者会存在冲突吗？

Start by reproducing the reported sequence: perform incremental lexical-analysis training, then load the custom dictionary and analyze text containing a dictionary-defined word. The issue names no files or tests, so first locate the training, model-loading, and custom-dictionary entry points; done means determining whether both inputs can be loaded together and whether the custom word affects analysis.
